I have Zef’s o rings too but like getting a shock unexpectedly I’ve yet to try them, I just use Rolock most of the time.I pack superglue to fix the holes in my glove..... so I don't have to change gloves, because I too have nightmares (and my wife still makes fun of me for that time gloves kicked my ass!!)
@Zef actually sent me some rings that are supposed to make the process 100% easier, but my superglue from before he sent them is still holding strong.
